Abstract
A nucleophile substituted unsaturated hydrocarbon based compound is prepared by reacting a compound of the formula: ##STR1## wherein R and R' are hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl, alkoxyalkyl, alkoxy, alkylthioalkyl, or carboxyalkyl or carboxyalkenyl and X is a leaving group selected from the group consisting of chlorine, bromine, and iodine with a nucleophilic reagent.
Claims
exact text as granted — not AI-modifiedWhat is claimed as new and is intended to be secured by Letters Patent is:
1. A method of synthesizing a nucleophile substituted unsaturated hydrocarbon based compound comprising: reacting a compound of the formula: ##STR9## wherein R and R' are hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl, alkoxyalkyl, alkoxy, alkylthioalkyl, carboxyalkyl, carboxyalkenyl, and X is a leaving group selected from the group consisting of chlorine, bromine, and iodine with a nucleophilic Ag + salt/H 2 O 2 reagent.
2. A method for synthesizing a nucleophile substituted fatty acid derivative, comprising: reacting a vinyl cyclopropyl group containing fatty acid or ester of the formula: ##STR10## wherein R" is hydrogen, alkyl, aralkyl, or alkenyl or aralkenyl containing at least one olefinic site; L is alkylene of 3 to 9 carbon atoms, optionally containing at least one olefinic site; R''' is hydrogen, alkyl, aryl or aralkyl and X is a leaving group selected from the group consisting of chlorine, bromine, and iodine with a nucleophilic Ag + salt/H 2 O 2 reagent.
3. The method of claim 1, wherein said leaving group X is bromine.
4. The method of claim 1, wherein said reaction is conducted at a temperature of 0° to 40° C.
5. The method of claim 1, wherein said reaction is conducted in a solvent of a dialkylether, a dialkylformamide, acetonitrile, trifluoroethanol, or dimethylsulfoxide.
6. The method of claim 2, wherein in said vinyl cyclopropyl compound reactant, said substituent R''' is methyl, R" is CH 3 (CH 2 ) 4 CH═CH--, X is bromine and L is --(CH 2 ) 6 --.
7. The method of claim 2, wherein said group R is n-butyl, said radical -L- is --CH 2 CH═CHCH 2 CH═CH(CH 2 ) 3 -- and R' is methyl.
8. A method for synthesizing a nucleophile substituted fatty acid derivative, comprising: reacting a vinylcyclopropyl group containing fatty acid or ester of the formula: ##STR11## wherein R'', R''', L and X are as defined above, with a nucleophilic Ag + salt/H 2 O 2 reagent.
9. A method of synthesizing a nucleophile substituted unsaturated hydrocarbon based compound, comprising: reacting a compound of the formula: ##STR12## wherein R and R' independently are hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl, alkoxyalkyl or alkoxy and X is a leaving group selected from the group consisting of chlorine, bromine and iodine with a nucleophilic Ag + salt/H 2 O 2 reagent.Cited by (0)
